"Coastal Aumaua" is a subrace in Pillars of Eternity.
It is one of the Sub-races you can choose for the Aumaua race
You choose your sub-race during Character Creation
Viewed as a warlike race, the Coastal Aumaua live in a mainland region along the coasts of the northern hemisphere - lands they conquered by pushing Thyrtan (meadow folk), Natlan (savannah folk), and orlan communities out.
Their culture is more centralized and urban than their island cousins, though both groups are involved in seafaring.
Coastal Aumaua are very rare in the Dyrwood, but those that do make the journey usually do so as mercenaries, bodyguards, or soldiers.
